Problem matlab 6.0 with 3D figures

My 3D figures in matlab don't show up ony more, only a black figure box comes up.
matlab
Xlib: extension "GLX" missing on display ":0.0".
Solution: Before running your 3D plot command you run: set(gcf,'renderer','zbuffer'), the 3D image will display correctly and very fast, too.

Selecting different page of a pdf-filed into a new pdf-file

Solution: pdftk input.pdf cat 1 2-5 7-end output output.pdf

Problem: Matlab always export my 3D figure to an eps-file that is build out of points instead of vectors. This results in a poor quality of the picture.

Solution: type in matlab print -depsc -tiff -r600 output
This give a nice quality eps-file as result were -r600 indicates the number of dots per inch.
